During cab signal failure en route in 554 territory, notification must be given to whom as soon as possible without delay to train?

• A. The Dispatcher
• B. The Dispatcher and Conductor
• C. The Maintenance supervisor
• D. The Public Safety Office

Answer: (B)

When a cab signal fails while running in territory where cab signals are inoperative, the on-board crew must immediately notify both the dispatcher and the conductor. The dispatcher needs to be alerted so they can arrange protection, issue any necessary instructions, and coordinate with other trains to maintain safe movement through the affected area. The conductor, being the supervising member on the train, must also be informed to coordinate the crew’s actions, implement the required protection procedures, and ensure everyone follows the approved method for proceeding or stopping under cab signal failure. Notification should be done right away, using the usual radio or communication channel, without delaying the train. Notifications to maintenance or public safety would be addressed through different procedures and are not the immediate, joint responsibility for this situation.
